I'm an Australian currently on a Tier 2 general Visa. I'm changing employers on Tier 2 visa- I gave notice 7 weeks ago (I'm a teacher hence the long notice period) and my contract will end with the current employer on 31st August. My new job is waiting for the new CoS to come through but have just been told it could be up to 18 weeks!? I am meant to be starting my new job in September however if this doesn't come through in time I may not be able to start the job.
My questions: 1) How long do I have after my visa expires on 31st August before I have to leave the UK?
2) Will I have to leave before this? Or is there a '28 day grace period' (I read about this on this website)
3) Can I apply for my new Tier 2 from anywhere outside the UK or will I have to go back to Australia to do so?
Any help on this would be greatly appreciated!
